Report Who is having problems with the PAC Audio SWI-PS??? in Problems/Troubleshooting Posted November 25, 2008 Mario, For those of us who currently own the SWI-PS, will there be a firmware upgrade we could flash or send the part in to be programmed to the latest? I'd like the ability to program my wheel's mute button to answer call instead. Main reason is so I don't have to take the hands off the wheel to answer a call, especially if the 2.0 firmware decides not to display the dialog on the first incoming call... Thanks!
